Reality TV tattooist Kat Von D claims that her former fiance Jesse James cheated on her with 19 different women before their breakup.

"Today I encountered the 19th girl to add to the list of people Jesse cheated on me with during this last year," she wrote in a lengthy post on her Facebook page titled "Thank you, Jesse James."

James, host of the Discovery Channel reality series "Monster Garage," had no official comment on his former fiancee's allegations of infidelity, but a source close to him called them "ridiculous," People reported Monday.

Today I encountered the 19th girl to add to the list of people Jesse cheated on me with during this last year.

In her Facebook post, von Drachenberg called the relationship "toxic" and said she had hoped to prove to "those who judged Jesse solely based on what they read in tabloids" that he was capable of change.

James' five-year marriage to actress Sandra Bullock ended in June 2010 after his affairs with tattooed stripper Michelle "Bombshell" McGee and other women were revealed.

He announced just months later that he was engaged to von Drachenberg.
